3 postgres processes

Hi,

After issuning initdb and starting the postgres server, I checked for processes running, expecting to see just one:

postgres  4926  4924   0 14:44:52 ?           0:00 /usr/postgres/8.2/bin/postgres
postgres  4924     1   0 14:44:52 pts/1       0:00 /usr/postgres/8.2/bin/postgres
postgres  4929  4850   0 14:44:56 pts/1       0:00 grep postgres
postgres  4928  4850   0 14:44:56 pts/1       0:00 ps -ef
postgres  4927  4924   0 14:44:52 ?           0:00 /usr/postgres/8.2/bin/postgres


Only one of them is in postmaster.pid. What the other ones are for?

 more /pg_data/postmaster.pid
4924
/pg_data
  5432001        31


Thanks,
